Each ToL leaf page provides a synopsis of the characteristics of
a group of organisms representing a leaf at the tip of the Tree of Life. The
major distinction between a leaf and a branch of
the Tree of Life is that a leaf cannot generally be further
subdivided into subgroups representing distinct genetic lineages.
